Definitions

  • the present apparatus is for automatically fitting on and removing tyres from all types of automobile wheels by laying a wheel horizontally on a driven table which can rotate and by operating a pedal the wheel is clamped or unclamped thereon. The pedal is then released and a tyre laid in a slanting position on the wheel and means guides and presses the bead of the tyre over the edge of the tyre rim for mounting purposes or a lever having an inverted conical rotary end is thrust between the wheel rim and the wheel of the tyre for removing the tyre from the wheel.
  • the present invention concerns a fully automatic apparatus for fitting on and removing automobile tyres.
  • the main advantage of this apparatus consists in the fact that it is enough to operate a single pedal both for clamping and unclamping the wheel and for causing the latter to rotate in both directions with respect to the fitting and removing means.
  • fitting and removal gears require only one single adjustment for making them fit to be used with any kind of wheel whatever, and that said fitting and removal means which come into contact with the tyre consist of rotary elements.
  • the apparatus substantially consists in the following combination: a table onto which the wheel in question is laid horizontally; a driving shaft onto which the table can freely rotate; a plurality of guiding arms mounted radially around the table; a driving device for moving aforesaid shaft in both directions; on each of the guiding arms, a claw which is movable along the length of the arm, which claws are collectively able to grip the rim of the wheel; a device mounted between said driving shaft and the claws for the radial displacement of the latter and rotation of the table; an arm mounted in order to be able to swing in a horizontal plane on top of aforesaid table; a vertical rod with height adjustment, mounted on the free end of said swinging arm; a device for fastening said rod in the swinging arm; at least one guiding roller for guiding the bead or beads of the tyre slightly beyond the edge of the rim, which roller is mounted so as to be able to rotate freely about a vertical

  • FIG. 3 illustrates, on an enlarged scale, a section by a plane the trace of which follows the straight line III-III of FIG. 2;
  • FIG. 4 illustrates, on an enlarged scale, a cross-section through the pressure roller
  • FIG. 5 illustrates, on an enlarged scale, a cross-section by a plane the trace of which follows the straight line VV of FIG. 1.
  • the apparatus comprises a cabinet 1 containing an electric motor which can rotate in both directions.
  • This motor is controlled by a circuit breaker 3 and a reversing switch 4 which can be put into the required position by means of a pedal 5.
  • the motor drives a reduction gear 6 of which the drive shaft 7 carries a sprocket wheel 8 which, in turn, drives over a hinged chain 9 the sprocket wheel 10 mounted onto shaft 11.
  • the latter passes through the top of cabinet 1 and rotates in a sleeve 12 fastened to the top plane of the cabinet 1.
  • a rotary table 16 consisting of two discs 17-18.
  • each guiding screw 21 which, on the one hand, turns in a ball bearing 22 mounted in a block '23 fastened between the two discs 17-18 of table 16, and rotates, on the one hand, in a bearing 24 located at the end of an open arm 25 which is part of block 23.
  • the three arms in question are mounted radially.
  • Onto each guiding screw 21 a small block 26 is screwed, which can move thereon in a to-and-fro motion and onto which is fastened a claw 27. These claws are able to grip the rim of the wheel which is 'being worked on, and to hold the latter fast onto table 16.
  • a column 28 which can rotate.
  • the top of this column carries a horizontal arm 29 onto which are mounted at the front two half-parts 30-31; this arm is traversed by an opening 32 with square cross-section into which a rod 33 of identical cross-section can be moved up and down and can be fastened.
  • the latter is provided on top with a handle 34.
  • Arm 29, as well as both halfparts 30-31 are traversed by a cross-opening into which moves a threaded rod 35 which carries a crank 36.
  • This threaded rod provided with a shoulder, bears in the halfpart 31 and screws into the threaded hole of half-part 30 which holds sliding rod 33.
  • the latter carries at the bottom two guiding rollers 37 which can turn about a vertical axis 38 and of which the annular face has a V- shape.
  • the object of this guiding roller is, when a tyre is being mounted, to run along the rim of the wheel and hence to determine the exact position of the guiding rollers 37 with respect to the peripheral edge of the wheel.
  • Rod 33 is also provided with a hook 45 in which a lever 46 can freely be hooked, which lever carries at one end an inverted conical roller 47 which is thrust into the bead or beads of the tyre when removing the latter.
  • lever 46 is simply introduced into opening 48 of cabinet 1.
  • the wheel to be fitted is placed horizontally onto disc 17 of table 16 and pedal 5 is depressed.
  • This causes the circuit of electric motor 2 to be closed so that the motor is set going, with the result that, by means of gearbox 6, the sprocket wheels 8 and 10, as well as hinged chain 9, shaft 11 which carries the angle pinion 19 begins to turn.
  • the three angle pinions 20 which engage aforesaid angle pinion 19, guide the guiding screws 21, which causes the blocks 26 with the claws 27 to move towards the rim until the latter is strongly held between the set of claws 27.
  • Pedal 5 is then released, which cuts off the electric circuit of motor 2 and brings the apparatus to a standstill.
  • the wheel For removing a tyre, the wheel is laid onto table 16 and fastened thereon by means of the claws 27, as described above. Ihe conical roller 47 of lever 46 is then thrust under the bead or beads of the tyre and column 28 is turned until said lever 46 can be hooked into hook on top of the wheel. Pedal 5 is then depressed in order that, as described above, the wheel should start rotating with the tyre, with the result that the bead or beads of the tyre are unrolled by the motionless lever over the rim. If then column 28 is rotated as described above, by lifting pedal 5, the claws 27 will release the wheel, as mentioned above, so that the latter can be removed.
  • An apparatus for fitting on and removing the tyres of automobile vehicles which apparatus mainly comprises: a table onto which the wheel in question is laid horizontally; a driving shaft about which aforesaid wheel can freely turn; a plurality of guiding arms mounted radially around the table; a driving device for moving aforesaid shaft in both directions; on each of the guiding arms, a claw which is movable along the length of said arm, which claws are collectively able to grip the rim of the wheel; a device mounted between said driving shaft and the claws, for radial displacement of the latter and rotation of the table; an arm mounted in order to be able to swing in a horizontal plane on top of aforesaid table; a vertical rod with height adjustment, mounted on the free end of said swinging arm; a device for fastening said rod in the swinging arm; at least one guiding roller for guiding the head or beads of the tyre, able to turn freely on a vertical axis mounted at the end of
  • An apparatus as defined in claim 1, comprising: a drive shaft; a table which is mounted onto said shaft in such a way that it is free to rotate; an angle pinion solidly fastened onto said shaft; several angle pinions engaging the angle pinion in question; several guiding screws mounted radially in a horizontal plane around aforesaid table, whereby each one carries one of said angle pinions; for each guiding screw a supporting arm fastened to aforesaid table; and on each guiding screw a little block provided with a screw thread which carries a claw, whereby the whole set of claws grips together the rim of the wheel.
  • An apparatus as defined in claim 1, comprising a swinging arm with a vertical and a horizontal part, whereby said vertical part is mounted in the cabinet of the apparatus in such way as to be able to rotate freely, whilst the horizontal part carries a rod which can be moved up and down and means for fastening it.
  • An apparatus as defined in claim 1, comprising: sliding rollers for guiding the beads of the tyre; an axis for said guiding rollers; and a flat part onto which is mounted aforesaid axis and which is mounted at the bottom of the rod which can be adjusted up and down.
  • An apparatus as defined in claim 1, comprising: a pressure roller; a recess at the back of the latter; a guiding roller fitted in aforesaid recess about a vertical axis, which roller runs along the peripheral edge of the wheel rim, whereby said guiding roller projects slightly beyond the rear face of the pressure roller.
